Weather in May
Temperature
The transition into May marks the average high-temperature at a hot 86.4°F (30.2°C), differing minimally from April's 81.9°F (27.7°C). Throughout the month of May, the nighttime temperature dips to an average of 66.7°F (19.3°C).Heat index
The heat index for May is estimated at a torrid 96.8°F (36°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.Heat index evaluations are typically in the context of light winds and shaded environments. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are largely significant for babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
